ABSTRACT:
The invention relates to a coating on a surface, including a carrier and a plurality of flakes dispersed therein. The flakes are oriented quasi-normally to the surface and have grooves extending quasi-parallel to the surface, wherein the plurality of flakes forms at least 50% of all grated flakes in the coating. The invention also relates to a method of aligning the flakes using external fields of different orientations.
